Adjustable and removable trigger

ABSTRACT

An Adjustable and Removable Trigger for firearms that allows trigger pull adjustments and is removable as a deterrent to unauthorized use.

BACKGROUND

1. Field of Invention

This invention relates to firearms and more particularly to anAdjustable and Removable Trigger assembly for improved firearm safetyand storage.

2. Description of Related Art

In the past firearm manufacturers used various adjustable triggerdesigns and external locks for gun safety. Firearms have used variousadjustable trigger designs for sometime, but the mechanisms have alwaysrelied on an additional external trigger lock to achieve both adjustableand secure functionality.

Browning, Beretta, and other firearms manufacturers have used variousadjustable trigger designs utilizing set screws to lock the trigger shoein position.

These trigger locks are generally bulky, two-piece clam shell designsthat come into the trigger area from both sides of the trigger guard andengage the lock thereby blocking the trigger from access and use. Indisplaying the gun the trigger lock is very utilitarian and detractsfrom the aesthetics of the gun, but does serve its role of preventingunauthorized use of the firearm.

DETAILED DESCRIPTION OF THE INVENTION

The main parts of the Adjustable and Removable Trigger are illustratedin FIG. 1's perspective view. These parts are 1 the Trigger housing, theRemovable assembly comprised of 2A the Removable trigger base, 2B theBall lock access hole, 2C the Trigger shoe, and 2D the two Adjustmentset screws.

The functionality of this invention is more fully illustrated in FIG.2's cut-away view of the Adjustable & Removable Trigger, FIG. 3A is anexploded view of the Adjustable and Removable Trigger parts and FIG. 3Bis an illustration of the Removable Assembly. The Removable assembly 2is comprised of the Removable Trigger Base 2A, the Trigger Shoe 2C, andthe two Adjustment set screws 2D. The Removable assembly 2 can beadjusted by loosening the two Adjustment set screws 2D and moving theTrigger shoe 2C to the desired position and then tightening theAdjustment set screws 2D to fix the position. This adjustment can bemade with the Removable assembly in or out of the gun.

The Removable assembly 2 inserts into the Trigger housing pocket for theRemovable assembly 1A and snaps into position by momentarily raising theBall lock ball 3C and once the Removable assembly is seated in thepocket the form of the Removable trigger base 2A allows the Ball lockball 3C under pressure from the Ball lock spring 3B to reposition sothat the Ball lock ball 3C locks the Removable trigger base 2A intoposition along with the whole Removable assembly 2.

Detachment of the Removable assembly 2 is accomplished by inserting thesame L-shaped Allen wrench used to tighten the Adjustment set screws 2Dinto the Ball lock access hole 2B and passing through the Triggerhousing hole for access to release the ball lock 1B and pushing up theBall lock ball 3C while rotating the Removable assembly 2 down and out.

The ball lock parts are located in the Trigger housing 1. The Ball lockball 3C is located in the Trigger housing hole for the ball lock spring& ball 1C. It is held there under light tension by the Ball lock spring3B which is held in the hole by the Ball lock set screw 3A which threadsinto the Trigger housing threaded hole for said screw 1D.

Adjustment, removal and placement of the Removable assembly iseffortless, an effective deterrent to unauthorized use of the firearmand does not detract from the gun's aesthetics.

1. What is claimed is: An Adjustable and Removable Trigger for firearms,comprising: a trigger shoe as a means for one to fire the gun, aremovable base as a means to join and adjust location of the triggershoe and the trigger housing, a ball lock mechanism as a means ofholding and releasing the trigger shoe from the firearm, whereby saidfirearm can be fired with said trigger shoe in place or rendereddisabled by actuating said ball lock mechanism and removing said triggershoe from the firearm.
